SAFETY RAZOB.

Application filed April 18, 1922. Serial No. 554,760.

To all whom it may concern:

Be it known that we, NELSON H. FAIR- WEATHER and LEROY H. CROSBY,citizens of the United States, residing at Everett and Waltham,respectively, in the county of Middlesex and State of Massachusetts,have invented new and useful Improvements in Safet Razors, of which thefollowing is a speci cation.

This invention is embodied in a safety razor of improved construction,adapted to be carried in a garment pocket, when not in use, and to bereadily converted into an gitudina edges of a head, the

operative razor, the construction being such that the blade-holding headmay be stored in one end portion of the structure, and a plurality ofblades in the opposite end portion.

Of the accompanying drawings forming a part of this specificat1on,-

Figure 1 is an end view of a razor embodying the inventgg n, adapted foruse.

Figure 2 isa side view of the same.

Figure 3 is a side view of the blade.

Figure 4 is a fragmentary perspective view, showing a portion of thehead.

Figure 5 is a longitudinal section showing the entire structure,including the head-con taining sheath hereinafter described, adapted forcarriage in a pocket.

Figure 6 is a section on line 66 of Figure5.

Figure 7 is a section on line 7-7 of Figure 5.

The same reference characters indicate the same parts in all of thefigures.

The head or blade-holdm portion of our improved razor is preferab y madefrom a blank of resilient sheet metal, bent to form a blade-rest portion12, a guard portion 13, extending downward and forward from the restportion, a resilient partially tubular neck 14, forming a socketportion, adapted to receive, the reinforcing back of the bladehereinafter described, and a clamping lip 15, which is normally held bythe resilience of the neck in yielding contact with the rest portion 12.The socket portion or neck 14, and the uard portion 13, form oppositelonength of which is much greater than its width, or the distancebetween said longitudinal edges. The guard portion is apertured for thepassage of lather through 1t, preferably by slots 17, as shown by Figure4, so that the guard portion has a continuous lower edge. The

clamping lip is immediately over the ridge formed by the junction of therest portion 12, and the guard portion 13.

Projecting inward from, and rigidly secured to the rest portion 12, is ashank 18, which is obliquely arranged or inclined relatively to the restportion. The width of the head between the socket and guard portions issuch that the head is adapted to be inserted in a cylindrical sheath 19,of a diameter suitable for carriage in a vest pocket, the longitudinaledges of the head bearing upon, or being in close proximity to oppositesides of the internal surface of the sheath, and the shank occupying aportion of the interior of the sheath at one side of the head, as shownby Figure 6. We are enabled by this arrangement, not only to enable ashank of suflicient operative length to be stored in a relatively smallsheath, but also-to enable the shank when en aged'with a cylindricalhandle'20, in accordance with our invention, to stand with the headinclined relatively to the longitudinal axis of the handle, as shown byFigure 2.

The handle 20 has a reduced portion 21 at one end, containing a socket22, which is coaxial with the handle, and is adapted to detachablyengage the shank 18, the socket and shank being preferablyscrew-threaded. The reduced portion 21 permits the insertion of theshank in the handle socket without contact between the guard portion andthe handle, as shown by Figure 2.

The blade 22 is flat-sided, and has a single cutting edge 23, itsopposite orback edge being inserted in a slot in a cylindricalreinforcing back 24. Said slot is formed to receive the back edge andminor portions of the sides of the blade, so that the major portions ofthe blade sides are exposed. The blade is therefore adapted to occupy aspace of minimum width between the rest 12 and the clamping lip or ear15. The back and blade are formed to be engaged with the head by slidingthe back into the socket portion 14, and the blade between the restportion 12 and the clampin ear 15. This operation expands the soc et andraises the car, which exerts a clam ing pressure on the blade.Displacement o the blade in all directions, excepting endwise,is-prevented by the he. To prevent acciden endwise displacement, weprovide the back 24 with a positioning depression 26 (Figure 3), andform an inwardly projecting positioning boss-27 (Figure 1) on the socketwall, adapted to spring into the depression when the blade is in itsoperative position, so that endwise pressure on the back is regui todisplace the blade from said osition.

The blade is narrow 1% its cutting edge projects sli htly forward fromthe rest 12, and over t e inner portion of the guard. 'lo permit theconvenient removal ot the blade from the head, the back 2% 1s ag thanthe blade, so that its ends project from opposite ends of the socketsuficicntly to form short handle portions 24, adapted to be grasped,these portions b6 preferably knurled, or otherwise corru etc The handle20 has a tubu ar end rtion forming a cavity 29, adapted to receiveseveral blades. A cap 30, forming an extension of said cavity, isremovably engaged with the handle. The depth of the cavity 29 is suchthat when the ca is removed, rtions of the blades project t erefroin, sot at they ma be t and remov.

s here sown. the handle is adapted to contain three blades, which may bearranged as shown by Figure 7. llnjurious contact of the blades witheach other is prevented by spacing members 32, which are separtitionsfixed to the handle. A lining 33 of thin sheet cork, inserted in thecavity, prevents injury to the cutting edges of the lades.

It I now M seen that the head, the handl and the sheath constitute asafety razor structure, the head and a set of the blades of which areadap to be he in the handle and shea, these to :u structure adapted tobe carried in a ,m -ut like a fountainn, and th adapted for use v a y ,i"i til shank We cl an:
